A banking application verifies a user's account balance before processing a withdrawal. However, due to a delay between the balance check and the withdrawal transaction, an attacker manages to initiate multiple withdrawals before the balance is updated, resulting in an overdraft. What type of vulnerability does this scenario illustrate?
Brute force attack targeting user authentication mechanisms.
Race condition allowing exploitation of timing gaps between operations.
SQL injection flaw due to improper query handling.
Cross-site scripting (XSS) vulnerability in the input fields.
This scenario illustrates a race condition, where the attacker exploits the timing discrepancy between checking the account balance and processing the withdrawal. By initiating multiple withdrawals in quick succession, the attacker takes advantage of the window where the balance hasn't been updated yet.
